Abstract

Pre-strains are often introduced into high temperature components, in the form of plasticity during the fabrication phase and creep deformation in the operation phase. Material pre-straining alters the mechanical properties and failure behavior of engineering components and structures; hence it must be characterized and considered in the structural integrity of high temperature components. The influence of plastic and creep pre-straining on the tensile, creep, fatigue and fracture behavior of an austenitic stainless steel has been examined in this study.
